Customize Which File Types Open in Office Web Apps

Issue:

In case the viewer service for a specific Office Web Apps format (Word, PowerPoint, Excel or OneNote) is disabled on the SharePoint server, SharePoint Integrator still opens files of this type in the web browser.

Cause:

SharePoint Integrator is unable to determine if the viewer service for a particular file type is enabled or disabled. If the "Open supported file types in Office Web Apps" option is enabled for the configured site in SharePoint Integrator, all documents of type Word, PowerPoint, Excel and OneNote open in the web browser.

Resolution:

You can configure SharePoint Integrator to use Office Web Apps to open document of a specific file extension. The file

{Lotus Notes installation folder}\framework\shared\eclipse\plugins\com.mainsoft.sharepoint.sidebar_{version}\shellprograms.properties

lists which file extensions are opened in Office Web Apps for editing and viewing. Each row in the file lists a file extension and its level of Office Web Apps support. The value "webapps" implies that the Office Web Apps application is capable of opening a read-only mode of the file type; The value "editwebapps" implies that Office Web Apps allows the user to edit documents of this type.

For example, to remove Office Web Apps support for PowerPoint files, when opened from SharePoint Integrator, set all rows starting with the extension "pp" to "webdav" only.

The default contents of the file are:

docx=webdav:webapps:editwebapps
doc=webdav:webapps
